Definitions

  • the invention relates to a test stand for an internal combustion engine, comprising a drive and/or load system, a force transmission device for connecting the internal combustion engine with the drive and/or load system, and a sensor and evaluation system for automatically collecting and evaluating measurement variables, wherein the force transmission device comprises a system for detecting torque and rotation angle, which system is coupled to the internal combustion engine in a torsionally stiff manner.
  • a test stand with a detachable coupling of a load unit for a hot test and a drive unit for a cold test of an internal combustion engine is disclosed.
  • an electrical multi-function aggregate can also be used.
  • Rotation angle measurements are quite common in the context of functional tests.
  • the rotation angle or crank angle can be derived from the torque curve of an ideal engine, which does not apply for real engines, however, so that here for torque measurement and rotation angle measurement, different sensors are used.
  • the object of the present invention was a test stand with a coupling between the test object and the system for detecting torque and rotation angle, which coupling is improved for exact measurements.
  • the test stand is characterized according to the invention in that the force transmission device has at least one vibration damper which is arranged on that side of the system for detecting torque and rotation angle which is opposite to the internal combustion engine.
  • the sensor system which comprises for example a torque measuring flange, is mounted in a torsionally stiff manner between the internal combustion engine and the vibration damper.
  • the force transmission device has at least one multi-disk clutch which is arranged on that side of the system for detecting torque and rotation angle which is facing the internal combustion engine.
  • the force transmission device has at least one torsion rod on that side of the system for detecting torque and rotation angle which is facing the internal combustion engine.
  • FIG. 1 shows an engine test stand in an overview and FIG. 2 shows a force transmission device according to the invention of said test stand in a larger scale.
  • An internal combustion engine 1 is connected to a drive 2 and/or load system 3 .
  • the internal combustion engine can be a gasoline engine or a diesel engine.
  • for driving in case of a cold test, and for inducing a load, in case of a hot test, separate electric machines can be used; however, a multi-function machine can also be used.
  • the internal combustion engine 1 is coupled with the drive and/or load system 2 , 3 via a force transmitting device 4 , wherein said force transmitting device 4 is illustrated in detail in FIG. 2 .
  • the system 5 for a non-destructive and play-free coupling of the internal combustion engine 1 to the force transmission device 4 also includes a sensor system 6 which is coupled to the internal combustion engine 1 in a torsionally stiff manner for collecting different measurement variables.
  • Said sensor system 6 which comprises at least one torque measuring flange and one rotation angle sensor is arranged between that side of a vibration damper 7 which is facing the internal combustion engine 1 and the system 5 for coupling to the internal combustion engine 1 .
  • Potentially provided multi-disk clutches 8 and/or a torsion rod 9 are preferably provided between the sensor system 6 and the system 5 for coupling to the internal combustion engine 1 .
  • one multi-disk clutch 8 is provided at each of the ends of the torsion rod 9 , wherein one multi-clutch disk 8 connects the torsion rod 9 with the system 5 , and the second multi-disk clutch 8 connects the torsion rod with the sensor system 6 .
  • the system 5 comprises a clamping collet 10 which is conically formed on the inside and which can be pushed by means of the spring force of a disk spring 11 over an internally toothed and longitudinally slotted clamping sleeve 12 which is conically formed on the outside.
  • a power takeoff shaft 13 of the internal combustion engine 1 which shaft is inserted in the clamping sleeve 12 , can be enclosed in a form and force fitting manner without user intervention.
